I have tried installing Windows Server 2008 R2 three-4 times today. I keep getting a blue screen after the boot disc gets to "Loading Windows" part. The code is 0x00000f4 (0x0000000000000003 , 0xFFFFFA8000925060 , 0xFFFFFA8000925340, 0xFFFFF8000C784DB0)

I am having a very frustrating problem with my new Dell XPS 8500's wireless connection - Dell Wireless 1703 802.11b/g/n (2.4GHz). Basically, I am losing my network connection every couple of minutes. The process goes something like this: 1) Not connected - Connections are available
